The US withdrawal will become effective at the end of December 2018 – until then, the US will remain a full member. The US will establish an observer mission at the Paris-based organization to replace its representation, the state department said.
Benjamin Netanyahu tweeted he had instructed his foreign ministry to “prepare Israel’s withdrawal… in parallel with the United States”.
The decision follows a string of UNESCO decisions that have drawn criticism from the US and Israel.
In 2011, the US cut its funding to UNESCO in protest at its decision to grant full membership to the Palestinians.
Last year, Israel suspended co-operation with UNESCO after the agency adopted a controversial resolution which made no reference to Jewish ties to a key holy site in Jerusalem.
The resolution also criticized Israel’s activities at holy places in Jerusalem and the occupied West Bank.
Then earlier this year, PM Benjamin Netanyahu condemned UNESCO for declaring the Old City of Hebron in the West Bank a Palestinian World Heritage site.
He accused UNESCO of ignoring Judaism’s ancient connection to the city, which includes the crypt where its matriarchs and patriarchs are buried.
Israeli soldier Elor Azaria, who was filmed shooting dead a wounded Palestinian attacker after he had been disarmed of a knife, has been convicted of manslaughter.
Sgt. Elor Azaria, 20, shot Abdul Fatah al-Sharif, 21, in the head while he was lying immobile on a road.
The incident happened in Hebron in the occupied West Bank in March 2016, after another soldier was stabbed.
Sgt. Elor Azaria said he thought Abdul Fatah al-Sharif might have an explosive vest, but prosecutors said his motive was revenge.
The high-profile trial has proven extremely divisive in Israel.
There have been rallies to support the soldier and some senior politicians backed Sgt. Elor Azaria. However, top military figures were quick to say that his actions did not reflect the values of the Israel Defense Forces (IDF).
In the incident on March 24, Abdul Fatah al-Sharif and another 21-year-old Palestinian, Ramzi Aziz al-Qasrawi, stabbed and wounded an Israeli soldier before troops opened fire on them, wounding Sharif and killing Qasrawi.

Footage of the scene several minutes later, filmed by a Palestinian and released by the Israeli human rights group B’Tselem, shows Abdul Fatah al-Sharif alive.
A soldier, identified as Sgt. Elor Azaria, is then seen cocking his rifle and fatally shooting Abdul Fatah al-Sharif from several meters away.
In their indictment, prosecutors said Sgt. Elor Azaria “violated the rules of engagement without operational justification as the terrorist was lying on the ground wounded and represented no immediate threat for the accused or others who were present”.
Delivering the verdict on January 4, the panel of three military judges rejected Sgt. Elor Azaria’s defense that he shot Abdul Fatah al-Sharif because he continued to pose a threat.
Elor Azaria had told the court that he believed there might be a suicide belt under the Palestinian’s jacket.
The judges, who took two-and-a-half hours to deliver their verdict, noted that Sgt. Elor Azaria’s commanders had testified that he did not mention the same concerns when they questioned him immediately after the shooting incident.
The judges also said there was no dispute regarding the veracity of the statements made by another soldier, who testified to military investigators that Sgt. Elor Azaria had told him during the incident: “They stabbed my friend and tried to kill him – he deserves to die.”
Elor Azaria told the court that he did not recall having any such conversation, but the head of the judging panel, Col. Maya Heller, described him as an “unreliable witness”.
She said: “His motive for shooting was that he felt the terrorist deserved to die.”
Prosecutor Lt. Col. Nadav Weissman said: “This is not a happy day for us. We would have preferred that this didn’t happen. But the deed was done, and the offence was severe.”
A spokesman for Sgt. Elor Azaria’s family said evidence proving his innocence had been ignored. “It was like the court was detached from the fact that this was the area of an attack,” he said.
His mother, Oshra Azaria, shouted at the judges: “You should be ashamed of yourselves.”
The defense team has said it will appeal against the verdict. Sentencing is expected in the next few weeks. Manslaughter in Israel carries a maximum 20-year term.
Abdul Fatah al-Sharif’s father Yusri was quoted as saying Sgt. Elor Azaria deserved a life sentence. Andul Fatah al-Sharif’s uncle, Fathi, told Haaretz that the decision to try him for manslaughter rather than murder was “a perversion of justice and of the court”.
A right-wing member of the governing coalition, Naftali Bennett, has called for an immediate pardon for the soldier.
The final decision lies with President Reuven Rivlin, who said in a statement that he would only deal with the issue once the judicial process had run its course.
